The only functioning airport in Tripoli reopened on Thursday following three hours of closure after missiles were fired at it, causing chaos and fear among passengers, airport authorities said.
No further details were immediately available. It was not clear whether any projectiles hit the airport its facilities or runways.
After the destruction of Tripoli International Airport, in factional warfare in 2014, Mitiga was the only airport operating domestic and international flights in the capital region of north-western Libya.
Mitiga was targeted with missiles on a number of occasions as OPEC member Libya descended into armed anarchy following the fall of Muammar Gaddafi in 2011.
On Thursday, artillery shells hit the Libyan capital eastern military forces are trying to capture in a near year-long war, killing a woman and injuring four others, a health ministry source told Reuters.
Libyan National Army (LNA) forces under former Gaddafi-era general Khalifa Haftar moved last April on Tripoli, where the internationally recognised government is based. International efforts to defuse the conflict have been fruitless.
